Unable to Access CRM by IP:port number inside network RRS feed

  • Question

  • Dear CRM Community,


    I want to thank you in advance for any and all help.  I can access the web client by its host header but I cannot access it by its IP/port number.  I am wanting sales reps to be able to connect to our infrastructure by VPN (Windows VPN/PPTP) and to use the Outlook Client for Laptops but if I can't access the CRM web client by IP/port number (inside or by VPN) then I doubt that they will be able to use the Outlook Client for Laptop and synchronize.

  • It is DNS resolve issue..


    See implementation guide for


    If CRM 4.



    Use IIS to set DNS.


    One solution is to have users connect to the CRM server by IP address, not domain name, and hence remove DNS from the equation altogether. Note that you'd also have to use Deployment Manager to change the Reporting Server URL to use the IP address.


    An alternative would be to configure your server (.20) to forward DNS requests to the router, and set clients to use the .20 server as the primary DNS server. This should allow users to connect to both CRM and web mail

  • I forgot to tell you that this is CRM 3.0.


    CRM will be accessed from inside the office and by VPN connection.


    I have used a Host Header record for the IIS 6.0 Website that I created specifically for the CRM installation.  Should I not have done this?


    Using the IP Address and port number does not allow me to access CRM Web client from inside the office nor when I am conencted by VPN.


    What do I need to do to allow remote users to connect to CRM using Outlook Client for Laptop using the VPN connection? 


    The Implementation Guide for CRM 3.0 and the CRM 3.0 Installation and Configuration training manual does not tell me what I should or should not do to get this to work.

  • I don't think that its a DNS issue. If it was accessible by IP but not by name, then it would have been an issue of DNS. Please correct me, if i am somewhere wrong in my logic.


    You need to give it a public IP to access it across the network using VPN etc. Lets resolve it step by step.

    what is machine IP on which your CRM is hosted? What is defualt Port # for your application hosted at IIS? can you access it using that http://IP: port inside your organization?

  • I had made a host header record in DNS and this would not allow me to access the Web Client by IP address once I had connected to our office by VPN.  When you use a VPN (Windows VPN) you cannot access a server by its server name or host header record so that leaves you using the ip address.  If you have a host header record setup then you can't access the site by ip address.  So if you are going to have remote users accessing your CRM by VPN remember to not use a host header becasue they will need to use the IP address.
